"I'm here at the Foxconn factory in Zhengzhou, where there was reportedly a strike over the weekend, although from what workers have told us, it's unclear whether if it was a strike or a smaller worker dispute. But one thing is clear, tensions here are high."

Mr. Zhu who has only been working here less than a month is getting ready to quit.

"Maybe Foxconn is a little bit better, but the wages they provide are nowhere near a living wage. Workers still have to struggle very hard to make a living, and you know, they're still working 10, 12 hours a day under quite oppressive and stringent conditions, and that's why you see these disputes cropping up time and time again."

For now Foxconn's Zhengzhou factory seems to be operating normally. But given the production pressures it faces and the massive scale of its China facilities, no one's ruling out further trouble.
